Piscataquis County District Attorney R. Christopher Almy said the charges stem from a case involving two children — one boy and one girl — roughly between the ages of 5 to 10 years old.

The children outlined for police how the defendant committed sexual crimes against them, said Almy on Monday afternoon. “This happened over a three-year period. When police investigated the case, the defendant gave a rather complete and detailed confession.”
